A man in Jacksonville, Florida, has been charged with a felony for making threats on social media about running over protesters, according to an announcement from the Jacksonville Sheriff’s Office on Wednesday.

Authorities reported receiving a tip regarding a social media user who commented that if they encountered any protesters in Jacksonville, they would “run them over with a tow truck.”

JSO’s Intelligence Unit was able to identify the user as 26-year-old Zachary Degross.

Investigators visited the home of Degross on Wednesday for an interview. Police stated that detectives gathered sufficient evidence to arrest him on a second-degree felony charge for sending written threats to commit an act of terrorism.

Online jail records showed Degross still in custody at the Duval County jail Wednesday at 5:15 p.m.

“Making a threat like the one Degross made is a felony,” JSO wrote on social media. “If you are making threats online to harm others, even if you don’t intend to follow through with that action, we will arrest you.”

Police encouraged anyone who sees online threats to report them.
